Answer:
Jack traveled 5 miles in 1 hour
Step-by-step explanation:
We have that
2r−9≤−6------> 2r ≤ -6+9-------> 2r ≤ 3-----> r ≤ 1.5
the solution is the interval (-∞, 1.5]
using a graph tool
see the attached figure
cos0 = √3/2
1 - cos²0 = sin²0
= 1/4 = sin²0
sin in quadrant 4 is negative
sin0 = -1/2
The measures that are true for the quilt piece include:
- a=. = 60°
- The perimeter of the rhombus is 16 inches.
- The length of the longer diagonal is 7 inches.
<h3>How to depict the information?</h3>
The value of a will be:
= 90° - 30°
= 60°
The perimeter will be:
= 4 × 4
= 16 inches.
The length of the diagonal will be:
= 2 × 3.46
= 6.92 = 7
